Fort Boyard: Ultimate Challenge is a Disney XD/CITV game show that premiered on October 17, 2011 in the United States and on January 1, 2012 in the United Kingdom.

The show is a challenge game where six teams of teenagers battle-to-the-finish to win the Ultimate Challenge and become "Conquerors of The Fort". The show is a revived version of the original Fort Boyard and was presented by Pair of Kings' Geno Segers and Laura Hamilton in the first two series. In May 2012, Fort Boyard: Ultimate Challenge was renewed for a third season. It was also revealed that Andy Akinwolere would be the new co-host, replacing Segers.

In the UK, the third series began on 8 December 2012 and is usually simulcast on ITV. All three series to date have aired in 2012 on ITV. In the USA, it will premiere in late 2013, with a broadcast date yet to be confirmed. Zodiak Media, the distributors of the show, have since split each Series 3 episode into 2x30 minute parts for foreign broadcasters including Disney XD.

The series is also being rolled-out globally on the Disney network.

A fourth series will begin airing in Autumn 2013 on ITV.
